    Increasing Resistance to the Negative Effects of Set

    Two experimental studies were reported in which attempts were made to increase resistance to the negative effects of set. Set interference was measured by performance on 1) a task in which a set was experimentally induced, 2) a series of problems presumed to involve implicit sets, and 3) a test of creativity presumed to involve implicit sets. The experimental treatments consisted of tasks which required set-breaking. An important aspect of this research was that no hints or instructions concerning sets were provided. The findings offer modest support for the view that learning experiences can be designed which will increase resistance to interference from set. Suggestions for future research on this problem were discussed. These experiments utilized a novel research design in which each group of subjects acted as both an experimental and a control group. Thus, each study was, in essence, two studies. The advantages and limitations of this design were discussed

    A Phenomenological Study of Irish and Portuguese Women’s Experiences of Receiving Family Support When Studying STEM Subjects at Technical Institutes

    This paper reports a research study of women’s experiences of receiving family support when studying science, technology, engineering, and mathematics (STEM) subjects at technical institutes in Ireland and Portugal. Specifically, it reports phenomenological analysis of 19 interviews conducted during the 2014-­2015 academic years with female students studying engineering subjects at technical institutes in Ireland and Portugal. It identifies forms of positive support received from family as well as problematic family dynamics and concerns. Parents, uncles, and aunts provide many positive forces, as do surrogates (i.e., adopted family and close mentors). Cousins and brothers also provide role models and information. For our participants, meeting family obligations and being first-­generation college students presents some challenges and stress

    Exploring the Impact of Brexit on UK’S Engineering Education Sector from the Perspective of European Students and Staff

    Get PDF
    The UK higher education attracts a far higher number of international academics from all over the world, who teach and do research, than any other country in Europe, being only surpassed by Switzerland [1]. Moreover, because engineering itself is considered a global field, this sub-field of higher education also relies on international mobility more than most academic disciplines in the UK The impact of the United Kingdom European Union membership referendum of June 2016, commonly referenced as the Brexit referendum, is still unfolding and under continuing analysis. However, it is widely anticipated that it will disrupt European student and staff mobility and may have negative repercussions for education, research and innovation

    Dissipative Tunneling in 2 DEG: Effect of Magnetic Field, Impurity and Temperature

    Full text link
    We have studied the transport process in the two dimensional electron gas (2DEG) in presence of a magnetic field and a dissipative environment at temperature T. By means of imaginary time series functional integral method we calculate the decay rates at finite temperature and in the presence of dissipation. We have studied decay rates for wide range of temperatures -- from the thermally activated region to very low temperature region where the system decays by quantum tunneling. We have shown that dissipation and impurity helps the tunneling. We have also shown that tunneling is strongly affected by the magnetic field. We have demonstrated analytical results for all the cases mentioned above.Comment: 8 pages, 2 figure

    The cytochromes of mitochondria from Tetrahymena pyriformis strain ST

    Full text link
    1. Mitochondria of the obligately aerobic ciliate protozoon, Tetrahymena pyriformis strain ST, are unusual in that they possess a cytochrome oxidase system that does not react with reduced mammalian cytochrome c; the presence of cytochromes a(603)+a(3) is masked in the α-band region of spectra by the broad absorption band of cytochrome a(620). 2. Other haemoproteins present include cytochromes b(560), b(556), c(553) and c(549). 3. The reaction of reduced cytochrome a(3) with CO is reversed by flash photolysis, and in the presence of O(2) the subsequent oxidation of this cytochrome is followed by that of cytochrome a(603). 4. Cytochromes a(620) and b(560) also react with CO and with KCN; the latter cytochrome corresponds with that designated cytochrome o by other workers. 5. The contribution of cytochrome a(603) to difference spectra is revealed by making use of the fact that it does not react with KCN. 6. Cytochrome a(620) is unstable, and its α-absorption band is lost from spectra of mitochondria which have been aged or treated with ultrasound, detergents or organic solvents. 7. Possible pathways of electron transport via the several different terminal oxidases in Tetrahymena mitochondria are proposed
